Other than Craftsy, a lot of the teachers from QU have gone over to Academy of Quilting, I think some of the classes might even be the same. The AoQ was started by Ruth Blanchett (formerly of QU) when QU closed.
I haven't used the Academy of Quilting so I can't comment on it's quality. I have used QU and Craftsy and both were good.
